numcaps in configuration

After a user report I noticed I should clarify: If you add, e.g. numcaps=10 to your configuration file you're changing the default number of captures but the default mode of operation is to capture at fixed intervals so to actually use this value you also have to add timecode_from=$TC_NUMCAPS to your configuration, which the changes the mode of operation to a fixed number of captures. E.g.:

$ cat ~/.vcs.conf
numcaps=20
timecode_from=$TC_NUMCAPS
cols=5
